Dr. Senkov earned his Doctorate Degree of Philosophy in Theoretical and Mathematical Physics in 2004 at Budker Institute of Nuclear Physics, Novosibirsk, Russia, and got a Masters Degree in Physics in 1998 and a Bachelors Degree in Physics in 1996 (both diplomas with Honors) at Novosibirsk State University in Russia. Some of Dr. Senkov's recent works are devoted to accurate calculation of nuclear level densities (NLD). Spin- and parity-dependent nuclear level densities represent an important ingredient for theory of nuclear reactions. Knowledge of the rates of certain nuclear reactions are extremely important for applications to nuclear astrophysics, where these rates determine formation, evolution, and the main properties of stars. In most of the cases relevant to nuclear astrophysics, where experimental information is not available, the reaction rates for medium and heavy nuclei can only be estimated theoretically. Dr. Senkov wrote two large-scale FORTRAN codes for calculations of NLD which allow for parallelization of computing. These codes were successfully tested on up to 6,000 processors (Phys. Lett. B702, 413 (2011), Comp. Phys. Comm. 184, 215 (2013)). The new algorithm Dr. Senkov developed for this project is about several thousand times faster compared to the previous one. Using Dr. Senkov's codes it became possible to calculate nuclear level densities for given spin and parity for practically any available Shell Model Hamiltonians and model spaces avoiding direct diagonalization. This provided a breakthrough in the methods for NLD calculations. Dr. Senkov is also very interested in neutrinoless double beta decay problem. Neutrinoless double beta decay, if observed, would prove that neutrinos are Majorana fermions, an important milestone in the search of physics beyond the Standard Model. In addition, one could extract more information about the nature of the decay mechanism and possibly determine the light neutrino mass hierarchy and the lightest neutrino mass.

At Columbia, Dr. Sheffield taught sections of the cross-disciplinary course Frontiers of Science -- covering topics in neuroscience, biodiversity, Earth science, physics, astronomy, evolutionary biology, and biochemistry -- while carrying out her research on the structure of the Milky Way.
Dr. John Toland received his Ph.D. in physics from Stevens Institute of Technology (Hoboken, NJ) in 2011 and his M.S. Degree in physics in 2009 from the same institution. Dr. Toland’s thesis research centered on modeling the rotational sensitivity of multiple interferometers connected in series. Dr. Toland explored the effects of size varying interferometers both due to random imperfections and chains with designed size variations. Dr. Toland received his Bachelor’s degree in physics form Humboldt State University (Arcata, CA) in 2005. Dr. Toland continues his research into simulating the transmission properties of multiple interferometers to determine how their geometry affects their rotational sensitivity. He is extending this work to explore the effects due to other geometric phase shifts subject to interferometer geometries studied with phase shifts associated with rotation. Dr. Toland is also exploring the possibilities of incorporating heavily parallel processer computation into his work; he is part of an ongoing interdisciplinary collaboration at Stevens Institute of Technology that has been recognized by NVIDA as a research center for parallel processing using the CUDA programming language. Doctor Toland has been teaching physics courses at LaGuardia since the Fall of 2012 and previously taught physics course ate CUNY: Kingsborough Community College and at Stevens instate of Technology. He has experience teaching both algebra and calculus based general physics courses and laboratories.
